Definitions
- This description relates to systems that store and use energy.
- this relates to cameras that are triggered by motion sensors.
- These types of camera are commonly known as “trail cameras,” “wildlife cameras,” “game cameras,” “scouting cameras,” etc.
- One example of a trail camera is described in U.S. Pat. No. 6,735,387, which is incorporated by reference herein.
- Typical trail cameras are powered by batteries, which must be replaced periodically. Trial cameras deplete batteries quickly. For example, trail cameral batteries may typically be changed within 60-90 days on some cameras.
- FIG. 1 is a block diagram of a camera system using capacitive energy storage.
- FIG. 2 is a block diagram of another example of a camera system using capacitive energy storage
- FIG. 3 is a block diagram of another example of a camera system using capacitive energy storage
- FIG. 4 is a block diagram of another example of a camera system using capacitive energy storage
- FIG. 5 is a block diagram of another example of a camera system using capacitive energy storage
- FIG. 6 is a block diagram of another example of a camera system using capacitive energy storage
- FIG. 7 is a block diagram of an exemplary camera.
- the present invention provides a novel way to power a trail camera using one or more high capacity capacitors charged by an energy source (e.g., solar panels, fuel cells, etc.).
- an energy source e.g., solar panels, fuel cells, etc.
- An exemplary power source based on capacitors is described in the parent application, published as U.S. Pat. No. 7,275,501 entitled “System and Method Using Capacitors to Power an Automatic Feeder System,” which is incorporated by reference herein.
- a trail cameral of the present invention is powered by one or more capacitors.
- the capacitors are charged by one or more solar panels.
- the tail camera is capable of operating without the use of batteries.
- the circuits described here can be integrated into a solar panel module where solar energy is stored in capacitors, converted to a usable voltage and current levels and delivered to the external power input connection (available on most wildlife cameras) via a cable.
- This module can also include a timer/clock circuit that a user can use to define specific times that power be delivered to run the camera.
- a timer/clock circuit that a user can use to define specific times that power be delivered to run the camera.
- a wildlife camera can be designed with the circuit(s) described which run continuously or until capacitor power is deplinished or a wildlife camera can be designed with a user selectable function that allows users to set predetermined times for the camera to become active, thus conserving energy for these priority times.
- FIGS. 1-7 are block diagrams of various examples of the present invention.
- FIG. 1 is a block diagram of a system 10 using capacitive energy storage.
- FIG. 1 shows a capacitive network 12 , which is coupled to solar panel(s) 14 .
- the capacitive network may be comprised of a single capacitor or multiple capacitors. Multiple capacitors could be placed in series, parallel, or in a series-parallel configuration. These configurations could exist as a single configuration or as multiple configurations depending on the voltage and current requirements of the operating circuit.
- FIG. 1 also shows control circuitry 16 and a trail camera 18 coupled to the capacitive network 12 and solar panel 14 .
- the control circuitry 16 may include circuitry to control the operation of the camera, as well as circuitry to control the charging and discharging of the capacitive network 12 .
- FIG. 1 also shows the connection of an external power source 20 , which may be used to as an alternative of charging the capacitive network 12 .
- the external power source 20 may include an external charger, a battery, a fuel cell, a generator, or any other desired device.
- the camera 18 may include a video/image capture device, a controller, a motion sensor, a flash, as well as the control circuitry, displays, keypads, etc.
- FIG. 7 shows a block diagram of an exemplary trail camera 18 .
- the present invention greatly reduces the required maintenance of trail cameras.
- Capacitor technology using high dielectric films such as, but not limited to “Aerogel” allow large amounts of energy storage to exist in relatively small packages.
- Capacitors have a much greater (almost infinite) number of charge and discharge cycles compared to batteries.
- Capacitors are also far less affected by temperature.
- the density of the energy storage of capacitors allows adequate energy storage in capacitor form to replace batteries in trail cameras. Given the longer life properties of capacitors, trail cameras using capacitors instead of batteries dramatically reduce required user maintenance.
- FIG. 2 is a block diagram of one embodiment of a camera system of the present invention. This example describes trail camera, but the is not limited to the example shown.
- the system 30 includes a series/parallel capacitive network 32 , such as the network described above.
- a solar panel 34 is used to charge the capacitive network 32 .
- a charging circuit 36 is used to control the charging of the capacitive network 32 .
- a DC-DC converter 38 is used to step the capacitor voltage up or down to obtain a steady power supply for the camera as the capacitor voltages drop.
- the DC-DC converter provides a voltage to both the timer/clock circuitry 40 and the power distribution circuit 42 .
- FIG. 3 also shows a user interface block 44 , which may include a display, lights, switches, keypad, etc., for use by a user to control the operation of the system 30 .
- FIG. 3 is similar to the example shown in FIG. 2 , except that a separate DC-DC converter is used by the power distribution circuit 42 .
- FIG. 4 shows an example with just a camera 18 powered by DC-DC converter 38 .
- FIG. 5 is a block diagram showing another embodiment of a camera system.
- FIG. 5 shows a block diagram of a system 50 that is similar to the systems described above, with a capacitive network for the DC-DC converter, user interface, and timer/clock circuitry.
- a second solar panel and charging circuit supplies power to battery(s) 32 B, which provide power to the camera 18 .
- FIG. 6 shows a block diagram of a system 50 where a camera 18 is powered by both a capacitive network 32 A and batteries 32 B.
- the camera can rely on battery power when no power is available from the capacitive network, which will increase the life of the batteries.
